Doug,

Just a quick question/confirmation, you are ok with the threshold not being exposed I the API, right?

Yes, I think I argued against exposing it initially :-)

A side-note on this: Suitable Object/Comparable versions of DualPivot sort might someday be better fits to the parallel split logic and locality patterns than current Arrays.sort. Vladimir and I discussed this briefly a few years ago, but I don't know if they were ever developed. Otherwise, on quick glance, despite the now-huge vertical-space usage :-), the updated webrev looks OK to me. -Doug
